Romans 15:20-24

and thus I make it my ambition to preach the gospel, not where Christ has already been named, lest I build on someone else’s foundation, but as it is written, “Those who have never been told of him will see, and those who have never heard will understand.” This is the reason why I have so often been hindered from coming to you. But now, since I no longer have any room for work in these regions, and since I have longed for many years to come to you, I hope to see you in passing as I go to Spain, and to be helped on my journey there by you, once I have enjoyed your company for a while.
